This live blog is led by a major Coalition departure and a tragic Sydney river death investigation, with additional updates on NDIS reforms and a High Court appeal. It reads as a snapshot of the day’s Australian political and social news.
This is like a news bulletin with several big updates at once. One politician says he is leaving his job, while police are trying to understand why a father and young daughter died in a river, and other stories are about health rules and a court case.
Analysis
Main developments
Liberal frontbencher Jonathon Duniam says he will quit politics before the next election and leave the Senate at the end of the year. In his statement, he says he has spent 25 years in politics, including 10 years as a Tasmanian senator, and wants to reverse his priorities and spend more time with family. The Guardian frames the move as a blow for opposition leader Angus Taylor at a difficult moment for the Coalition, which is dealing with poor polling and competition from One Nation.
Sydney investigation
The live blog also reports that the body of a seven-year-old girl was recovered from Sydney’s Parramatta River after her father was found dead earlier the same day. Police say the man, believed to be the father in his 40s from the Westmead area, had hired a vessel earlier in the day. Investigators have established a crime scene and are examining the boat while trying to determine whether the deaths were accidental or deliberate.
Wider policy context
Other updates in the live blog focus on the National Disability Insurance Scheme and a High Court appeal by the founder of Giggle for Girls. Health minister Mark Butler argues the NDIS has become too large and costly and needs reform to protect its future, while disability advocates warn the changes could cause harm. The live format means the page is tracking several national stories at once, but the political departure and the river deaths are the strongest immediate threads.
Key points
- Jonathon Duniam says he will leave the Senate at the end of the year and quit politics before the next election.
- The Guardian says the move is a setback for Angus Taylor as the Coalition faces poor polling and a challenge from One Nation.
- Police are investigating the deaths of a father and seven-year-old daughter found in Sydney's Parramatta River.
- The live blog also covers Mark Butler's defense of NDIS changes and a High Court appeal bid by Giggle for Girls.
- Butler says the NDIS must be reformed to protect its future and control costs.
If the NDIS changes do what Butler says they will, the program could stay strong while better protecting the support people rely on. Duniam's planned exit could also give the Coalition a chance to refresh its team before the next election.
Advocates fear the NDIS changes could cut support in ways that isolate disabled people or leave them more vulnerable. On the political side, Duniam's departure could deepen the Coalition's problems if it cannot steady its leadership and polling.
